Leviticus 27:19-21

19If the one who consecrates it should ever wish to redeem the field, then he shall add one-fifth of your valuation price to it, so that it may pass to him.

20Yet if he will not redeem the field, 1but has sold the field to another man, it may no longer be redeemed;

21and when it 2reverts in the jubilee, the field shall be holy to the Lord, like a field 3set apart; 4it shall be for the priest as his 5property.
